Already last month, El-Enany appeared to cool down the expectations that rose after his predecessor Mamdouh Eldamaty revealed there was a "90 percent chance" that King Tut's tomb concealed two chambers.

Indeed, Eldamaty had confirmed that analysis of radar scans carried out by Japanese specialist Hirokatsu Watanabu revealed two hidden spaces on the north and eastern walls that could contain metal or organic material.

Begun last summer, the investigation inside King Tut's burial follows a claim by Nicholas Reeves, a British Egyptologist at the University of Arizona. He believes the hidden chambers contain the remains, and possibly the intact grave goods, of Queen Nefertiti, wife of the "heretic" monotheistic pharaoh Akhenaten, Tutankhamun's father.

Reeves speculated that the tomb of King Tut was not ready when he died unexpectedly at 19 in 1323 B.C.; consequently, he was buried in a rush in what was originally the tomb of Nefertiti, who had died 10 years earlier.

Friederike Seyfried, director of the Egyptian Museum and Papyri in Berlin, described Reeves's claim as a mere hypothesis and argued the radar survey can't prove the existence of a hidden tomb.

"The sudden death of the boy-king led the tomb's builders to finish the tomb quickly and close it up, which is why a cavity was found," he told Ahram Online.
